Résumé
(from the chapter) multiplication and division of positive integers and rational numbers may be considered relatively simple from a mathematical point of view / the research reviewed in this chapter, however, reveals the psychological complexity behind the mathematical simplicity / in particular, this complexity is manifested when the operations are considered not just from the computational point of view, but in terms of how they model situations
the chapter is in four parts / in the first, the range of applications of multiplication and division is set out, and the corresponding variety of external representations for the operations is illustrated / in the second part, the complexity is demonstrated further by reviewing current theoretical frameworks that treat the topic from several different perspectives / there follows an outline of a broader framework, the key points of which are that (a) multiplication and division model many distinguishable classes of situations, and (b) a fundamental conceptual restructuring is necessary when multiplication and division are extended beyond the domain of positive integers / [considers] the potential of computer representations, putting forward suggestions for the improvement of teaching about multiplication and division (PsycINFO Database Record (c) 2007 APA, all rights reserved)
